# Datatypes

data NP (a :: k -> Type) (b :: [k]) where #

An n-ary product.

The product is parameterized by a type constructor `f` and indexed by a type-level list `xs`. The length of the list determines the number of elements in the product, and if the `i`-th element of the list is of type `x`, then the `i`-th element of the product is of type `f x`.

The constructor names are chosen to resemble the names of the list constructors.

Two common instantiations of `f` are the identity functor `I` and the constant functor `K`. For `I`, the product becomes a heterogeneous list, where the type-level list describes the types of its components. For ``K` a`, the product becomes a homogeneous list, where the contents of the type-level list are ignored, but its length still specifies the number of elements.

In the context of the SOP approach to generic programming, an n-ary product describes the structure of the arguments of a single data constructor.

Examples:

    I 'x'    :* I True  :* Nil  ::  NP I       '[ Char, Bool ]
    K 0      :* K 1     :* Nil  ::  NP (K Int) '[ Char, Bool ]
    Just 'x' :* Nothing :* Nil  ::  NP Maybe   '[ Char, Bool ]

newtype POP (f :: k -> Type) (xss :: [[k]]) #

A product of products.

This is a 'newtype' for an `NP` of an `NP`. The elements of the inner products are applications of the parameter `f`. The type `POP` is indexed by the list of lists that determines the lengths of both the outer and all the inner products, as well as the types of all the elements of the inner products.

A `POP` is reminiscent of a two-dimensional table (but the inner lists can all be of different length). In the context of the SOP approach to generic programming, a `POP` is useful to represent information that is available for all arguments of all constructors of a datatype.

cata_NP :: forall {a} r f (xs :: [a]). r ('[] :: [a]) -> (forall (y :: a) (ys :: [a]). f y -> r ys -> r (y ': ys)) -> NP f xs -> r xs #

Catamorphism for `NP`.

This is a suitable generalization of `foldr`. It takes parameters on what to do for `Nil` and `:*`. Since the input list is heterogeneous, the result is also indexed by a type-level list.

The difference compared to `cata_NP` is that the function for the cons-case can make use of the fact that the specified constraint holds for all the types in the signature of the product.

Anamorphism for `NP`.

In contrast to the anamorphism for normal lists, the generating function does not return an `Either`, but simply an element and a new seed value.

This is because the decision on whether to generate a `Nil` or a `:*` is determined by the types.

Since: 0.2.3.0
